In the last episode, I had received the main parts of a Michelson Interferometer (the mirrors) and had roughly set them up using Lego stands. In the past couple of weeks I have been working on making a more stable and adjustable platform for this interferometer. Read More...

My school has had a Michelson Interferometer for many years, and I always show it to my grade 12 students to help explain the Michelson-Morley experiment - the one that showed that the speed of light does not depend on the motion of the observer. I showed this interferometer to some other Physics teachers on the February 2016 PD day in Ottawa. They were very interested and wanted to show their students. So I thought I would find out if I could build a similar and very inexpensive interferometer. Read More...

Lasers are quantum light sources and they are everywhere. But what is quantum about them? The PhET simulation is a great tool to give students a feel for the quantum process called stimulated emission. Read More...

Today the Nobel Prize in Physics was awarded to Canadian physicist Arthur McDonald for his work on neutrino oscillations. Chris Meyer heard about it while driving to work, and talked about it with his first period class, but little did he suspect that before noon he would be interviewed by CBC Newsworld!
